DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clean bench,
In particular, it is used for animal and plant and physicochemical laboratory operations that require a sealed and controlled environmental space, for example,
The present invention relates to a clean bench having a small housing width and installed in a limited space such as a spacecraft, an aircraft, and a submarine.

[0002]

2. Description of the Related Art Generally, a clean bench is required to be operable by an experimenter in addition to hermeticity, ventilation and cleaning of internal gas, and the like.

[0003] In order to perform experiments by manipulating the internal equipment while keeping the internal airtightness from the outside, usually, a plurality of airtight gloves are attached to the front or side of the housing. The position and the interval greatly affect the operability.

[0004]

The position of the glove is determined in relation to the position of the equipment inside the glove.
Since it is ergonomically determined by the width of the shoulder, etc., the glove width becomes narrow on a clean bench with a narrow housing installed in a limited space, and operability is sacrificed. In other words, how to secure the ergonomically necessary glove interval in a housing that is so narrow that the ergonomically necessary glove interval cannot be ensured is a problem.

[0005] The present invention has been made in view of the above points,
It is an object of the present invention to provide a clean bench in which a glove interval can be widened and a suitable operability can be ensured even in a clean bench having a narrow housing width.

[0006]

SUMMARY OF THE INVENTION According to the present invention, one or both sides of a front part of a housing are fan-shaped with a vertical hinge attached to a corner part of the front part of the front part of the housing at a maximum of 90 degrees on the front side. Expanded, a clean bench or an enclosure provided with a hole for internal operation gloves in the unfolded part, a front part and a rear part, and a horizontal part penetrating this front part of the enclosure to the rear part perpendicular to the front part. It is characterized in that it is a clean bench configured to rotate 90 degrees around an axis and convert the vertical and horizontal directions of the front part to each other.

[0007]

According to the present invention, a part of the side surface of the housing is unfolded to the front side so that the width of the front surface is widened, and a hole for the glove is provided in that portion. It can be made wider and suitable operability can be secured.

In general, the vertical dimension of the housing is sufficiently large compared to the width in consideration of the passage and height of the human. Therefore, when the casing is laid down, gloves can be installed at necessary and sufficient intervals. The object of the invention is likewise achieved.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments.

FIGS. 1 and 2 show one embodiment of the clean bench of the present invention. In this embodiment shown in the figure, first, the housing front part 2 is pulled out from the housing rear part 1 in order to avoid hitting both sides of the apparatus. An expansion joint 3 is provided between the rear part 1 of the housing and the front part 2 of the housing in order to maintain the airtightness.

A hinge 4 is vertically attached to the front corner of the front part 2 of the housing, and the unfolded part 5 on the side surface can be unfolded 90 degrees to the front side by the hinge 4. Another expansion joint 6 is provided between the housing front part 2 and the developing part 5 and in order to maintain the hermeticity of the hinge 4 part, and a glove hole 7 is opened in the developing part 5 and a glove 8 is attached. ing.

The width of the front surface of the housing front part 2 is narrow, and when two gloves 8 are provided, the interval is insufficient to ensure good operability. The width of the front surface has been increased, and a necessary and sufficient interval can be secured.

If necessary, another glove 9 may be provided on the front surface of the front part 2 of the housing.

FIGS. 3, 4 and 5 show another embodiment of the present invention. In the present embodiment, the cylinder 1 penetrating through the housing rear portion 1
In order to secure the required withdrawal distance along
1, the housing front part 2 is drawn out to the front side via the cylinder 12. A bearing 13 is attached to the outer periphery of the cylinder 12, and the outer periphery of the bearing 13 is supported by a cylinder 14 attached to the back surface of the housing front part 2. As shown in FIG.
A keyway and a stopper are provided between the cylinder 10 and the cylinder 11 and between the cylinder 11 and the cylinder 12 so as not to rotate or pull out too much.

When the pulled out front part 2 of the housing is rotated clockwise by 90 degrees as viewed from the front, the front and rear parts of the housing 2 are switched, as shown in FIG.
Can be made larger than the width of the housing rear portion 1.

Further, since the front part 2 of the housing is pulled out from the rear part 1 of the housing and further rotated by 90 degrees, the rear part 1 of the housing and the front part of the housing independently maintain the hermeticity. The spaces are connected by a pipe 15 wound spirally.

With such a configuration, the same effect as in the above-described embodiment can be obtained.

[0018]

According to the clean bench of the present invention described above, one or both sides of the front of the housing are fan-shaped with the vertical hinge attached to the corner of the front front of the housing as an axis. Side at a maximum of 90 degrees, and a clean bench or a case with a hole for internal operation gloves in the expanded part, or the housing is divided into a front part and a rear part. It is a clean bench that is configured to rotate 90 degrees around a horizontal axis that penetrates through and convert the vertical and horizontal directions of the front part to each other. And a clean bench can be obtained which can secure suitable operability.
